PRODUCT DESCRIPTION

Interface Specifications

LX-300+/1170

Revision F † Auto:

1.3.4 Interface Selection The printer has 2 interfaces; the parallel interface and serial interface. These interfaces are selected manually by Default Setting or selected automatically.

† Manual Selection

Communication is carried out in the conventional mode until a magic string (1284.4 synchronous commands) is received. By receiving a magic string, communication in IEEE1284.4 packet mode is started.

† Off:

One of 2 interfaces can be selected by Default setting.

Communication is carried out in the conventional mode. A magic string (284.4 synchronous commands) is discarded.

† Automatic Selection The automatic interface selection is enabled by Default Setting. In this automatic interface selection mode, the printer is initialized to the idle state scanning which interface receives data when it is powered on. Then the interface that receives data first is selected. When the host stops data transfer and the printer is in stand-by state for the seconds specified by Default Setting, the printer is returned to the idle state. As long as the host sends data or the printer interface is in busy state, the selected interface is let as it is.

† Interface State and Interface Selection

NOTE: The packet protocol of IEEE1284.4 allows a device to carry on multiple exchanges or conversations which contain data and/or control information with another device at the same time across a single pointto-point link. The protocol is not, however, a device control language. It does provide basic transport-level flow control and multiplexing services. The multiplexed logical channels are independent of each and blocking of one has no effect on the others. The protocol operates over IEEE1284.

When the parallel interface is not selected, the interface gets into a busy state. When the serial interface is not selected, the interface sends XOFF and sets the DTR signal MARK. When the printer is initialized or returned to the idle state, the parallel interface got into a ready state, the serial interface sends XON and sets the DTR SPACE. Caution that the interrupt signal such as a -INIT signal on the parallel interface is not effective while that interface is not selected.

1.3.5 Prevention Hosts from Data Transfer Time-out Generally, hosts abandons data transfer to peripherals when a peripheral is in busy state for dozens of seconds continuously. To prevent hosts from this kind of time-out, the printer receives data very slowly, several bytes per minute, even if the printer is in busy state. This slowdown is started when the rest of the input buffer becomes several hundreds of bytes. At last, when the input buffer is full, the printer is in busy state continuously.

1.3.6 IEEE1284.4 protocol The packet protocol described by IEEE1284.4 is ed on the parallel I/F. Two function modes of IEEE1284.4 protocol, “Off” and “Auto” are available, and one of them is selected according to the value of Default setting. (See 1.4.2.3 "Default Setting")

† When CSF is used: The uncertainty of the paper end detector may vary the number of printing lines within the same paper size. To avoid this, when CSF is used, page length measurement calculates the printable lines and if the paper is longer than the printable lines, the number of printing line is considered the printable lines (fixed value). When paper is shorter than the printable lines, the printer prints the fixed number of lines by forms over-ride function (which allows the fixed number of lines to be printed even when RPE detector detects paper end).

BPE DETECTOR BPE detector is installed right under the platen. The table below shows the BPE detector specifications.

Revision F

5.1 Overview C H E C K P O IN T

This chapter explains the adjustment required after disassembling the printer.

5.1.1 Required Adjustment This section describes the adjustments required after specified parts are removed or replaced. The following table shows the parts removed/replace and corresponding adjustments required.

The main board is different between LX-1170 and LX-300+. The C406 Main board is for LX-1170 and C294 Main board is for LX300+. In our main board assembly manufactory, common data related with the model name is stored in the specific address of the EEPROM on both main boards (C406 & C294 main board) and the common data is for the LX-300+ model name. So, in case you exchange the main board with the service parts on the LX-1170, you have to change the model name to LX-1170 by the above mentioned operation. This operation is not required for LX-300+
